For instance, you bought a new laptop with DDR4 RAM and want to add more memory to it by inserting a DDR3 RAM module from your older laptop.
Are DDR3 and DDR4 laptop memory (RAM) compatible?
Thats a common question when it comes to memory upgrades.
Unfortunately, that cant be done.Sorry bro, your bad luck started here.DDR3 uses a voltage.5V (or.35V for DDR3L variant).It is more power efficient and generally faster, but doesnt noticeably improve overall performance nor battery life of notebooks.And a DDR4 stick is incompatible with a DDR3 slot.DDR4 RAM: DDR3 RAM: If you observer the notch in is betonline a good poker site DDR4 and DDR3, it is given at two different places to avoid the wrong insertion, apart from notch the pins in DDR4 is slightly more when compared with DDR3 and the power consumption of DDR4.DDR3 and DDR4 laptop memory are not compatible / interchangeable.A DDR3 laptop memory module has 204 pins, whereas DDR4 has 260.Have a glance below.Also, the number of pins doesnt match.DDR4 memories have far different design from DDR3.
Finally, DDR3 memory is a bit shorter than DDR4.66 versus.74 inches.
Hence, DDR4 RAM is not backward compatible with, dDR3 motherboards/slots and vice versa.DDR3L is a dual voltage capable memory Sodimm, which supports operation at both.5V and R3 works.5v only while DDR4 consumes.2v R3 RAM uses a 240-pin connector, while DDR4 RAM uses a 288-pin connector.Besides the physical differences, DDR3 and DDR4 RAM differ in voltages.Also the small nab in the slot that seperate the pins in two pieces and it helps that we are installing it in right way(I hope you will understand) is in different place.As a side note, DDR3 and DDR4 dimms arent compatible neither.The same applies to corresponding bumps in the RAM slots on notebooks motherboards.You wonder if thats possible.First of all, a DDR3 laptop RAM module cant physically fit into a DDR4 laptop RAM slot and vice versa.Note: If you see sodimm in specs of both DDR3 and DDR4 laptop memory, that doesnt mean they are compatible.For nyxee's question, DDR3L is different from DDR3 and DDR4 as it can work on a voltage range.So, a DDR3 memory module wont fit in a DDR4 slot.
